Hippo pathway, which has been identified as a promoter of drug resistance, cancer progression, and metastasis in several cancer types, including squamous cell, mesothelioma and papillary kidney cancers.
In vivo, treatment with NXP900 inhibited primary and metastatic tumor growth in xenograft models of breast, cervical, esophageal, head and neck and medulloblastoma cancers, and demonstrated on-target pharmacodynamic effects. Furthermore, it has been found that YES1 gene amplification is a key mechanism of resistance to Epidermal Growth Factor Receptor (“EGFR”) or (Human Epidermal Growth Factor Receptor 2 and anaplastic lymphoma kinase inhibitors. A recent, peer reviewed study published in Nature Communication (not sponsored by the Company) demonstrated that NXP900 is able to re-sensitize resistant non-small cell lung cancer (“NSCLC”) cells to osimertinib (Tagrisso®), the leading EFGR inhibitor used for the treatment of EGFR mutation-positive NSCLC, when used in combination with Tagrisso®.
We have completed the IND enabling preclinical studies and the IND for NXP900 is currently pending.
Since our inception in 2020, we have devoted all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, acquiring product candidates and securing related intellectual property rights and conducting research and development activities. We do not have any products approved for sale and have not generated any revenue from product sales. We may never be able to develop or commercialize a marketable product. We have not yet successfully completed any pivotal clinical trials, obtained any regulatory approvals, manufactured a commercial-scale drug, or conducted sales and marketing activities.
Results of Operations
From our inception on July 27, 2020, through March 31, 2023, we did not generate any revenue. Our main activities through March 31, 2023 have been organizational and capital raising activities, the completion of the in-license agreements for our two drug candidates, NXP800 and NXP900, our Clinical Trial Application by the Medicines and Healthcare Regulatory Agency, preparation for the Phase 1a and Phase 1b clinical trials for NXP800, which commenced in December 2021 and April 2023, respectively, and beginning our IND-enabling studies for NXP900, which commenced in late 2021. Additionally, we completed our initial public offering in February 2022 and a private placement offering in July 2022.
Research and Development Expenses
Research and development expenses include costs directly attributable to the conduct of research and development programs, including licensing fees, cost of salaries, share-based compensation expenses, payroll taxes, and other employee benefits, subcontractors, and materials and service used for research and development activities, including clinical trials, manufacturing costs, and professional services. All costs associated with research and development are expensed as incurred.
Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will increase substantially in connection with our ongoing and planned preclinical and clinical development activities in the near term and in the future. The successful development of our product candidates is highly uncertain. At this time, we cannot accurately estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of any of our product candidates and we may never succeed in obtaining regulatory approval for any of our product candidates.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and personnel-related costs, including stock-based compensation, for our personnel in executive, finance and accounting, and other administrative functions. General and administrative expenses also include legal fees relating to patent and corporate matters; professional fees paid for accounting, auditing, consulting, and tax services; insurance costs; travel expenses; and facility costs not otherwise included in research and development expenses.
We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research and development activities.
